Hi,
I have a situation where my XC40 hands free speaker does not work properly. Instead of a normal sounding conversation it has a high pitched whine and sounds like electronic static. If I take the phone out of bluetooth and hold it up to my ear, the call is normal, so it's definitely the car speakers. Any thoughts on what might be causing the issue? The only way to resolve it that I can figure out is to stop the car, open/close the door and restart.
